That's nothing, on uPlay I have a mess of accounts where my new games are on an account where the email doesn't even exist anymore and old games are on my newer account on gmail address, with no way to transfer them together. Reason being that uPlay logged me, automatically, in my old account and bound the serial to that when I installed the game via external installers.

So yeah, all hail the new age of.. stupid as hell "every publisher for 'emself" digital platforms.
